With series 24V (nominal) panels you might exceed the max input V of the controller? My controller's max input is 100V, Vmp of many (72 cell) 24V panels is ~36V.
May not be a big deal with just 3 panels. But with 4 24V 72 cell panels, I wouldn't do it.
My Voc is 112V. 4 panels would be 150V and not good for my MPPT60 150V controller limit for example.
Ah right, that makes sense. My panels have a Voc of ~44V, so 3 would exceed the controller's 100V max.
